Hello everyone!

I am having an issue with my bootable USB:(.
If i try to boot from my USB (Kali Linux but i also tried Windows ) i press the esc & F9 (HP ProBook 4720S) it flashes for less than a second and then the PC boots into the Windows on my HDD.
This is how it happend:

I had Kali Linux with USB Persistence up and running on it but i needed to install windows on another PC so i formatted the USB and installed the ISO image of the windows 7 installer onto my USB. Since then the problem keeps occurring. Screen flashes and than reboots into Windows.
After this i tried to install Kali Linux ISO using universal USB installer. I know the installer works because i used it before to install Kali Linux. Same problem.
I know it's not the laptop because i tried to boot on my other PC (The windows one i got to work with a CD) and it is just the same problem.
Any help?

I tried it with LiLi but i still have the same problem! I did notice in that splitsecond i saw the underscore!

Edit: I tried to install it on another USB with both installers and it worked just fine so it is a problem with the USB.
I can acces thr USB and drop files on it without any problems.

Any other advices?
Thanks already!
